A CLI running `claude login` inside the container binds a random ephemeral
loopback port and hands the provider a redirect pointing at it. The browser
is on the host, so the callback lands on a closed host port and the login
hangs with no diagnostic. The auth bridge is the thing that fixes this --
it mirrors container loopback listeners onto the same host port -- so
having it default to off made a hang the out-of-the-box experience.
`auth_bridge_enabled` now defaults to true through a
`default_auth_bridge_enabled()` serde helper, matching the shape already
used by `use_shared_auth_token`. Because the default is applied at
deserialisation, projects stored before the bridge existed pick it up too;
`migrate_from_value` writes neither flag, so nothing defeats it, and a
regression test pins that.
Separately, `BrowserViewManager.enabled` was in-memory only and the durable
`browser_view_enabled` field on the project record was never implemented.
Rather than sync the two, the cache is removed and the record becomes the
single home for the flag, mirroring how `AuthBridgeManager` already works.
`stop()` deliberately does not clear it, since container teardown and
migration reach that path and neither is the user changing their mind.
Durable does not mean auto-started: a restarted app reports enabled with
the viewer off.
